Blackberry 8820 Safety And Product Information page 13

Potentially explosive atmospheres: Turn off all wireless connections on the
BlackBerry device when in any area with a potentially explosive atmosphere, and
obey all signs and instructions. Sparks in such areas could cause an explosion or fire
resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly
marked. They include fueling areas such as gasoline or petrol stations; below deck
on boats; fuel or chemical transfer or storage facilities; vehicles using liquefied
petroleum gas (such as propane or butane); areas where the air contains chemicals
or particles, such as grain, dust, or metal powders; and any other area where you
would normally be advised to turn off your vehicle engine.
Do not use the phone on the BlackBerry® device to report a gas leak in the vicinity
of the leak. Leave the area and, if the phone is available and active on the BlackBerry
device, make the call from a safe location.
Blasting areas: To avoid interfering with blasting operations, turn off all wireless
connections on the BlackBerry device when in a "blasting area" or in areas posted:
"Turn off two-way radio". Obey all signs and instructions.
